Only alternates registered as an alternate in the specific contest can substitute into that contest. If they are registered in a different contest, they cannot crossover to substitute in a contest they were not registered as a contestant; or a substitute prior to the registration deadline. Notification to the contest superintendents, and the CDE student coordinators is requested prior to the contest day. In the event of an emergency, please contact Matt Kreifels at (402) 617-1419.
